Abstract In this work, VO₂ thin films were prepared on the quartz glass substrates by using high power impulse magnetron sputtering. As-deposited films had a typical metal-insulator transition (MIT) and the lowest phase transition temperature was only 32 ℃. The X-ray diffraction patterns revealed that the lattice distortions in the as-deposited VO₂ (M) films were different, and the MIT temperature decreased with the interplanar spa-cing difference between the VO₂ (M) (011) and standard VO₂ (R) (110). According to the experimental results, the crystal structure and density of states in MIT of the VO₂ were studied by the ab initio molecular dynamics to evaluate the influence of the lattice distortion on the MIT temperature. The results showed that the crystal structure in the MIT was gradually transformed from initial VO₂ (M) to the VO₂ (R) with the increase of the temperature, coupled with the decrease of the band gap near the Fermi energy. In the end, VO₂ supercells were completely transformed into the metallic state, in which the Fermi energy is occupied by electrons. Furthermore, the MIT temperature was also related to the difference in the interplanar spacing between the initial VO₂ (M) (011) and standard VO₂ (R) (110), and the less the difference in the interplanar spacing, the lower the MIT temperature, which might be the nature resulting in the reduction of the MIT temperature.
